ACETYLENE-GAS GENERATOR.

Specicaton of Letters Patent.

Patented Apr. 8, 1913.

Application filed February S, 1912. Serial No. 676,397.

To all whom- 2'15 may concern.'

Be it known that I, LAszL JANowszkY, a subject of the King of Hungary,and resident of the city of Toronto, in the county of York and Provinceof Ontario, Dominion of Canada, have invented certain new and usefulImprovements in Acetylene-Gas Generators; and I hereby declare that thefollow- `ing is a Jfull, clear, and exact description of the same.

The object of my invention is to devise an acetylene gas generator inwhich the pressure of the gas within the gas tank can be utilized toautomatically start and stop the generation of gas, and this object isattained by the construction hereinafter set fort-h and particularlypointed out in the claim.

In the drawings: Figure l, is a vertical section of the generatorshowing the relative position of the various parts. Fig. 2, is aperspective view of the carbid holder. Fig. 3, is a plan view of theinternal support for the gas cylinder, and Fig. 4, is a section on theline a-a Fig. l.

Like characters of reference refer to like parts throughout thespecification and drawings.

The generator consists essentially of a cylindrical casing a, providedwith a removable cover a, a gas tank Z) having an enlarged base b', anda carbid magazine c provided with a removable bottom or holder 'l'. Thegas tank Z) is centrally contained within the cylindrical casing a andextends through the' removable cover a, the bottom of its base b beingprovided with feet d resting on the bottom of the cylindrical casing a.and holding the bottom of the gas tank Z) slightly above that of thecylindrical casing, the wall of the base b being provided with aperturese for the water to circulate into and out of the gas tank.

Supported upon the feet d is the ashholder g, comprising, as shown inFigs. 1

and 5, a bottom f with two concentric and imperforate rings L, L,extending vertically from the inner surface of the bottom f, the purposeof the rings h, h being to prevent the gas pressure within the gas tank,forcing the ashes contained in the ash-holder through the apertures einto the cylindrical casing a. The rings 7L, h may be of the sameheight, but it is preferable to make the outside ring 7L of a lowerheight than the inside ring, as by doing so, it is possible for the, gaspressure within the gas tank to force a part of the volume of water onthe outside of the ring lz. from the gas tank into the cylindricalcasing, as hereinafter described, and thus increase the storage spacefor the gasc Extending vertically from each of the rings L, it', is aperforate plate or screen i, z" respectively, the top edges of which areabove the plane of the bottom of the carbid holder 1^. Thevgas tank b isperfectly gas and air-tight when the cylindrical casing a is filled orpartly lled with water, and to provide for the generation and How of thegas, a screw-threaded aperture j is formed through its top o, andinserted in the aperture y' is the screw-threaded stem 7c of the gascock Z, connected by a short vpipe fm, with the vgas purier o.

The gas ypurifier is provided with a gastight cover 0 and has aconnection with the gas mains p to convey the gas to the burners of thelighting system. lVithin the gas purifier o is a filter, consisting of asponge g, a layer of charcoal g", and a layer of cot* ton batting g, thepurpose of the sponge being to absorb the moisture vfrom the gas as itpasses from the -gas cylinder to the gas mains, the purpose of thecharcoal being to dry the gas after passing through the sponge, and thepurpose of the cotton batting being to eliminate any particles of solid.matter which may have passed through the sponge and charcoal, so thatthe gas, after passing through the purifier to the mains, will be, forall practical purposes, clean and cry.

The carbid magazine c, having a closed top o and an open bottom c3, issubstantially of corresponding shape, but of smaller dimensions than thegas tank, and is so suspended within the gas tank as to provide a ychamber or duct for the passage of the gas to the stem of the gas cock.On the outer surface of the frusto-conical part c near its bottom edge,are pins c, as'shown in Fig. 2, to connect the carbid holder r to thebottom of the carbid magazine.

The carbid holder r consists of a ring 1 of corresponding diameter tothe bottom of the carbid magazine, and this ring r is provided withbayonet-joint slots r to receive the pins c4 projecting from the outersurface of the carbid magazine and thus removably connect the carbidholder to the carbid magazine. Within the carbid holder ico Cil

is a centrally located pyramid s, which, together with the sides s andbottom s oit' the carbid holder, are of a wire basket formation, thepurpose of which is to expose a relatively large surface of the carbidin the carbid holder, so that the water can obtain tree access to it.

Riveted to the outer surface of the top of the carbid magazine is aconnecting element z5 having a screw-threaded ring t for connection withthe screw-threaded stem la, by means oi' which the carbid magazine isheld suspended within the gas tank.

To maintain its central relation with respect to the gas tank, the outersurface of the carbid magazine is provided with spacing members o whichengage the inner surface of the gas tank h and thus vinsure anunobstructed passage for the gas. On the outer surface of the carbidmagazine c is a sloping collar ec located above the top of the carbidholder r for the purpose of shedding from the carbid holder anycondensation of the moisture carried into the gas tank by the gas.

Surrounding the gas tank is a resisting ring engaged by the lower ring yof the support fz the ring g/ being connected to the support y by meansof rods y. In the support y, as shown in Fig. 4, are peripheral slots eto clear the stationary lugs e on the inner surface of the outercylinder a when the support is being placed in position. It is necessaryto use a resisting support to prevent the gas pressure in the carbidmagazine and gas tank lifting them out. of the cylindrical casing.

In the use of the invention, the carbid magazine is charged with carbidpreviously treated with fat or fatty compounds to render it imperviousto atmospheric humid ity, and the carbid magazine with its holder, gastank, and other related parts are then placed in position within thecylindrical casing a, the support y then, by means of the slots e,passing down below the lugs e, until the ring y engages with theresisting ring 0c, the support 'Lz/"then being turned to bring the slotse out of line with the lugs a. rIhe cylindrical casing is then filled orpartly filled with water and the cover a is then placed in position.Owing to the presence of air in the gas tank, the water is prevented bythe air pressure coming into contact with the carbid in the carbidholder until the gas cock Z is opened. When the gas cock is opened, theair passes out of the gas tank through the puriiier and into the gasmains, and when the burners are opened, escapes to the atmosphere. Thewater then rising in the base of the gas tank, comes into Contact withthe carbid in the carbid holder, and the generation of gas proceeds andcontinues while the gas cock remains open and the liurners are takinggas. When the gas cock Z is closed or all ot' the burners are closed,the pressure of gas in the gas tank forces the water in its base throughthe apertures c into the cylindrical casing and thus holding it awayfrom the carbid in the carbid holder, prevents the further generation ofgas until the gas cock has again been opened. In this way, I obtain anautomatic control over the production of gas, which enables me toproduce only sutlicient for immediate consumption, thus enabling me toeconomize the use of the carbid and effect a corresponding reduction inthe cost of illumination.

The water in the cylindrical casing a, not only provides for thegeneration of gas, but it also forms a seal to render the escape of thegas from the gas cylinder impossible, except through the gas cock Z tothe purifier and mains.

Having thus fully described the nature oi' my invention, what I claim asnew and desire to secure by Letters Patent, is:

In an acetylene gas generator, in combination, a carbid magazine, and acarbid holder therefor, said carbid holder comprising a reticulated ringof shape corresponding to the bottom of the carbid maga-zine, areticulated bottom for said ring, and a centrally located reticulatedpyramid supported upon said bottoni, and means to detachably connectsaid carbid holder' to the bottom of said carbid magazine.
